Miami's internet is a mix of cable, fiber, and 5G home internet, with big differences between new high-rises and older neighborhoods. Most of the metro has a fast option, but it depends on your building and area.
What the Public Data Says
City-level speeds vary by provider and technology more than by any single average. For how Miami compares nationally, the Ookla Speedtest Global Index and BroadbandNow publish metro-level availability and speed data, and the FCC's Measuring Broadband America program tracks real-world US broadband performance. These are more reliable than any single test for comparing neighborhoods.
Major Internet Providers in Miami
Major providers include Xfinity (cable), AT&T (fiber/DSL), Hotwire (fiber in some communities), and T-Mobile/Verizon 5G home internet.
| Connection Type | Typical Download Range | Notes |
|---|---|---|
| Fiber | 300 Mbps – 1 Gbps+ | AT&T, Hotwire in wired buildings/communities |
| Cable | 100 Mbps – 1 Gbps | Xfinity — the main cable option |
| 5G home | 50 – 300 Mbps | T-Mobile, Verizon |
High-Rise vs House
In Miami's condo towers, the building's wiring and provider deal often decide your options; in single-family areas, cable or fiber is typical. Test wired at your address and compare with your plan.
How to Test Your Speed in Miami
The number that matters is your own connection, at your address. Run a speed test on a wired Ethernet connection, with other devices paused, at a couple of different times of day. Then compare your result with your plan's advertised speed. If it's consistently well below, read why your speed is lower than your plan and work through our slow internet guide before you call your provider.
